THE OVERVIEW OF TECHNOLOGY IMPLEMENTATIONS ON INTENSIFYING OF OIL PRODUCTION AND THE INCREASE OF OIL RECOVERY IN WORLD OIL FIELDS

Abstract

At the final stage of development hydrodynamic, physical and chemical methods to increase oil recovery are mainly used. The analysis of technology implementations on intensifying of oil production was carried out, and increasing volumes of oil recovery indicates the significant number of these methods. Today there are favorable conditions for the usage of physical and chemical methods of oil production intensification. The composition of surfactants and their usage at fields that are in the early stages of development is known. The final stage of field development is characterized by a number of specific features that make it difficult to extract oil (depletion of reservoir energy, high water cut of reservoir production, deterioration of bottom-hole formation zone, intensification of corrosion processes, scaling and others). Therefore, physical and chemical methods that were used at the early stages of field development are not fully suitable to be implemented in fields that are at the final stages of development. This proves the need for additional studies of physicochemical methods for the intensification of oil production at the final stages of field development.
